Good skiing can still be found on shady aspects.  Be aware of your exposure to steep solar aspects as Friday is expected to bring sunny skies and a freezing level up to 2900m.  The danger rating can increase rapidly by midday on solar aspects.

Weather Forecast

More warm weather forecast for the next few days. The freezing level on Friday is expected to rise again to 2900m along with clear skies. Today, solar aspects became moist and turned into a crust once the sun went away; expect the same thing for tomorrow. The winds are forecast to be 30km/hr from the West.

Avalanche Summary

No new avalanches were observed along the Spray road. One size 2.5 slab avalanche, NE aspect was observed in the Bow Valley in the north bowl of EEOR (Mt. Rundle).

Snowpack Summary

Wind slabs are most noticeable near ridgeline and extending down the slope on most aspects due to the recent winds. Today was warm and sunny, thus making the snow moist on solar aspects and turning into a crust once the sun went away. The November crusts are still a concern, mostly in shallow areas.
